Ileo-Sigmoid Knotting Rare Cause of Acute Intestinal Obstruction.

Ileo-sigmoid knotting (ISK) is a rare and potentially life-threatening condition that results in a double-loop intestinal obstruction involving the ileum and sigmoid colon. This case report delineates the clinical presentation of a female patient aged 38 years, who exhibited significant abdominal discomfort and distension, recurrent attacks of vomiting, and absolute constipation. Clinical and radiologic findings suggested bowel obstruction with signs of volvulus. Exploratory laparotomy confirmed type 1A ISK with gangrene of the distal ileum and a redundant sigmoid colon. Surgical intervention included resection terminal ileum with ileocecal anastomosis and sigmoidectomy and colorectal anastomosis. The patient recovered without complications. Timely identification of medical conditions and immediate implementation of surgical interventions are vital to a favorable prognosis.
